Hello,
I've got access to two Bridgeport CNC's with dead BOSS controls and stepper motors on them. I'm looking into trying to put on a new control on one or both.

What is the tool holder (#30 taper I read somewhere) that is needed to fit these things? Can you still buy them? Where? Is there more than one type of spindle that Bridgeport used on these older cnc's or all they all the "quick change collar" type?

The spindle has the "quick change" collar that you have to align with the toolholder and tighten with a spanner wrench that draws the tool up into the spindle taper.

Just wondering, if I can't find toolholders then they are worthless to me. Thanks.
